EJECTING MECHANISM FOR CORK-BLOCKING MACHINES.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed October 27. 1917. Serial No. 198,842.

To all whom it may concern:

Be it known that I, EMILIO Annnn'rr, a citizen of the United States, anda resident of the city of New York, in the county of Kings and State ofNew York, have invented certain new and useful Improvements Mechanismsfor Cork-Blocking Machines, of which the following is a specification.

The present invention relates to cork blocking machines,-and moreparticularly to those elements thereof which are used for removing thefinished products from the cutters, or in other words to the ejectingdevices thereof. I

In one type of these machines an ejector in the form of a rod is provitending throughthe rotary arbor and cutter of the machine and being heldin position The rod is held stationary within the arbor and Cutter. Thecutter, in completing its stroke toward the work, blocks out a cork fromthe cork strip, the said cork remaining within the cutter, to be removedtherefrom by the ejector, when the cutter moves in the oppositedirection. An ejector of this type has several defects, one of the samebeing the following: The diameter of the rod must be considerablysmaller than the inner diameter of the cutter, as otherwise it could notextend through the arbor, and for this reason it will not eject from thecutter chips or broken cork pieces entering the same. hose chips or corkpieces seriously interfere with the cutting operation. Another defect ofthe ejectors heretofore in use consists in that the ejector vibrates orswings within the arbor and cutter inasmuch as the same is supporte atone of its ends-only. Due to-this vibration or swinging motion, theblocker becomes very noisy.

The main object of the present invention is to provide an ejectingmechanism which effectively obviates the defects above mentioned.

With these and other' objects in view, which will more fully appear asthe nature of the invention is etter understood, the same consists inthe combination, arrange ment, and construction of parts hereinafterdescribed, pointed out in the appended ded, said rod ex-- claims andillustrated in the accompanying drawings, it being understood that manychanges may be made in the size and proportion of the several parts anddetails of construction within the scope of the appended claims withoutdeparting from the spirit or sacrificing any of the advantages of thelnventlon.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings in which Figure 1 is a central verticalsection taken through a portion of a corkblocking machine provided withan ejecting mechanism constructed in accordance with the presentinvention; Fig. 2 is a top plan view thereof; Fig. 3 is a centralhorizontal section taken through the cutting mechanism and the ejectortherein; Fig. 4 is a sim'lar section showing the elements in otherpositions; and Fig- 5 is a perspective view of a portion of the ejectingdevice.

In the drawings only so much of the cutting mechanism has been shown asis necessary to understand the function and operation of the ejectingdevice. Attention is called to the fact that, whileherein the ejectingmechanism has been shown mounte on a blocking machine of a particulartype, (the one described in application for Letters Patents, Serial No.157 ,489, filed on the 26th day of March, 1917, by myself, MichaelGaritj and Gaetano La Femina), it maybe used in connection with othersjust as well.

Referring now to the drawings, the'numeral 10 designates a portion ofthe main or supporting frame of the machine. Upon the table portion ofthe frame rests a base 11, from which rise bearings 12, in which isrotatably and reciprocably mounted a tubular arbor 13. This arbor isprovided in its front end with an interiorly screw-threaded portion 14,into which fits the screwhreaded end of a tubular cork cutter or ife 15For rotating the arbor and cutter, there is held between two of thebearings 12 a pulley 16, provided with a key 17 that is seated in alongitudinal slot 18 in the arbor. Rotation may be imparted to thepulley in any suitable manner. To properly perform the cutting ooration, the cutter is not only .ro-

tated but also reciprocated.

The cutter rewithin the bore of the arbor.

ciprocating means includes a lever 19, provided with a fork-shaped upperend 20, n engagement with pins 21. upon a ring 22, the latter beingloosely mounted upon the arbor between two stops 23. The lever isoscillated from the main driving shaft of the machine (not shown).

The work holder 24 posed upon the table frame, and may be of tion.

The ejecting mechanism comprises three elements, towit: a piston 25within the cutter, a rod 26 within the arbor, and a stop 27 that isattached to some stationary part of the machine. The piston 25 fitssnugly the bore of the cutter and is slidably disposed within thecutterl5 and has attached thereto or made integral therewith a rearwardlyextending stem 28, that projects through a hole 29 in the rear head 30of the cutter into the tubular arbor 13. The stem 28 is, screwt-hreaded,.as clearly shown at 31, threads mesh those of two of themachine is dis portion of the main any suitable construcnuts 32 and .33,said nuts bein disposed he nut 32 appear, as astop,

serves, as will hereinafter Upon and the nut33 as a locking means.

. the freeend of the stem 28 is mounted a 3 Ports secured The bracketnut 34, heldin positionby a cotter- N This nut serves its enlargementaiding with that pin 35. as an abutment. The rod 26 is loosely mountedwithin the tubular arbor, and is adapted to bear against an enlargement36 of a bar 37. This bar and constitute the stop 27 above referred to..he enlargement 36 is disposed Within the the same and also of that ofthe bar 3'? coinof the arbor 13. The bar secured to a bracket 38,adjustably held upon supto the rear bearing 12. 38 is provided with alongitu- 37 1s adjustably which, in turn is dinal slot 40, merging intoregistering th a hi e hthe arbor 13, th

serve to hold the upon the supports notches 41, through which extendsthe bar Clamping screws 42 serve tohold the bar 3? in position upon thebracket. The bracket is slidably disposed upon the sup ports 39, whichare made in; the form of rods having screw threads 43. Nuts 44, bearingag'ainst two faces of the bracket, same in proper position 39.

The operation of the. device is as fol lows Each cutter of the set withwhich is furnished is provided with itspiston 25 and the parts carriedthereby. efore. placing a cutter in position upon e stop nut 32 and thelock nut 33 on the stem 28 of the ejector are shifted on the stem sothat the stop nut 32 p s on 252s substan ially fiiish rith h he saidcutter After t cut tubular arbor, the axis of cutter, and th ter and theejecting mechanism now described has been put upon the arbor, the saidarbor and elements movingtherewith are shifted to the end of the idle orreturn stroke (Fig. 4). The clamping screws42 are then loosened, and thebar37 brought into engagement with the rod 26 and shifted until the saidrod is in a position in which the piston 25 is about flush with thecutting edge of the cutter. The clamping screws are then screwed down,to hold the bar 37 in this position. The device is then ready foroperation.

On the working stroke, both the arbor 13 and the cutter 15 thereon movetoward the work support. The cutter, in completing its forward stroke,blocks out a cork from the strip 45 (Fig. 3), the said cork causing thepiston 25 and the parts attached thereto to move rearward that is to saytoward the The corkremains within the .cutter and is removed therefromby the ejecting mechanism, when the cutter moves in the oppositedirection. Asthe cutter moves in the direction mentioned, the nut 34 onthe stem 28 first comes into contact with the rod 26, causing the latteralso to move rearward until it is by the enlargement 36 of soon asthenod 26 is stopped, 1t arrests the motion of the piston 25,'which, as thecutter completes its idle stroke, ejects the cork from the cutter. Thefinished product falls into a chute, to slide into a receptacle belowthesame, (the chute and receptacle are not shown). i

Inasmuch as the piston fits snugly the bar of the tubular cutter, brokencork pieces or chips are conveniently ejected from the us cannotinterfere with the proper operation of the machine. The bar 37 is tooshort to oscillate or swing, so that unnecessary noises are avoided inoperation. 7

What I claim is:

wardly projecting stem extending through said hole, an abutment upon theouter end of said stem, and a stop upon said stem intermediate saidabutment and the outer face of the head of'said cutter. V p
